Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Founding ML Engineer - **Company:** SONIBEL INSTRUMENTS INC - **Location:** San Francisco, CA, United States - **Salary:** $75,000.0 - $140,000.0 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Amazon Web Services, Amazon Elastic Compute Cloud, Amazon S3, ARM Architecture, Audit Trail, Big Data, Continuous Integration, Data Security, Software Debugging, Linux on Embedded Systems, Embedded Software, Firmware, Field-Programmable Gate Array (FPGA), Signal Processing, Management of Software Versions, Data Storage Technologies, ONNX (Open Neural Network Exchange) Format, Machine Learning Operations, Front End Software Development, TensorRT, Hardware Infrastructure - **Published:** June 7, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=914c8fe0e0d57b86 ## About the Role Do you have experience in Embedded software?, * Experience with embedded AI (TensorRT, ONNX Runtime, NCNN, OpenVINO, or similar edge inference stacks) * Audio or time-series ML (signal processing, STFT, mel spectrograms, acoustic event detection) * MLOps experience (experiment tracking, model registries, drift monitoring, CI/CD for ML) * Frontend or full-stack experience - we need customer-facing dashboards that surface model performance, defect history, and real-time alerts to operators and quality managers. If you can build that, you'd own it end-to-end and it's a core part of the product * Industrial AI, robotics, NDT, or field deployment of ML systems * Experience shipping a model to production and maintaining it post-launch * Embedded Linux or firmware familiarity ## Description * Design and operate Sonibel's ML experiment loop end-to-end: dataset versioning, training pipelines, agent-driven hyperparameter search, evaluation, error analysis, and repeatable research infrastructure * Run experiments autonomously by forming hypotheses, training models, interpreting results, identifying failure modes, and deciding what to try next without waiting for direction * Maintain and evolve cloud and GPU infrastructure for training, large-scale data preprocessing, and distributed experiment orchestration * Manage data storage, versioning, and pipeline artifacts on AWS (S3, EC2, and related services) keeping datasets, models, and experiment outputs organized, versioned, and accessible Edge deployment and optimization * Quantize, prune, and optimize models for real-time inference on embedded hardware (ARM Cortex, embedded Linux, FPGA targets) * Build the production pipeline: train * evaluate * package * test * deploy to edge devices in the field, with automated regression checks at each stage * Profile latency and memory on target hardware; understand the tradeoffs between model quality and inference budget at the hardware level Edge hardware collaboration * Deploy and validate models on embedded hardware in the field. You own the last mile from packaged model to running inference on the device * Collaborate with our hardware team on integration questions: understand the data path from sensor to model input well enough to debug end-to-end issues without needing to own the firmware yourself * Flag inference requirements (memory, latency, power) early so they can inform hardware decisions upstream Field deployment and data * Run data acquisition sessions independently: collect high-quality welding audio, debug sensor anomalies, manage hardware in industrial environments * Support customer pilots including first installs, sensor placement, operator training, on-site debugging, and post-deployment monitoring * Turn field feedback, failure modes, and data quality issues into better datasets and better models; close the real-world feedback loop continuously Data security and compliance * Maintain awareness of data security and privacy requirements for industrial ML deployments (at-rest encryption, access controls, audit logging) * Support compliance discussions with enterprise customers and help our CPO, Hooman satisfy security requirements during pilots and commercial rollouts Product and strategy * Contribute to customer-facing ML features and product decisions as one of the first people building Sonibel's core intelligence layer * Help define evaluation standards, deployment criteria, and model governance as we scale from pilot to production across multiple industrial verticals These will change based on what's working best in the field. Overall, we want someone to own the full arc from raw field data to a deployed, monitored, improving model, working directly alongside our CTO, George and collaborating with the hardware/firmware team when needed. The ideal candidate: * Wants to build ML systems that work in the real world, on a shop floor, inside a noisy enclosure, on hardware with tight memory and power budgets, not just in notebooks or on benchmark datasets * Is comfortable running the full experiment loop independently: forming a hypothesis, writing the pipeline, training the model, reading the results, and deciding what to do next without being handed a plan * Cares about speed, latency, and memory as much as accuracy. A model that can't run where it needs to run isn't a model, it's a prototype * Is comfortable deploying models onto edge devices and debugging what breaks between the trained model and the running device. You've poked at a sensor with an oscilloscope, or you're the kind of person who would. You don't need to write firmware, but you should understand enough of the hardware stack to collaborate effectively with the hardware/firmware team * Thinks about the whole system: training, versioning, packaging, deployment, monitoring, field feedback. You've felt the pain of a model that worked in training and broke in the field and you know how to prevent it * Is excited by messy real-world data, not discouraged. Sensor noise, inconsistent environments, imperfect labels, and hardware quirks are problems you want to solve * Is willing to put on a hard hat and go to a shipyard, a structural steel fab, or a construction site to understand what's actually happening. Industrial context is something you'll learn and care about * Takes ownership and follows through. You want real responsibility, not a backlog of small assigned tasks ## Related Videos - [Tour de Force: Open-Source LLM Inference Optimization from Simple to Sophisticated](https://www.wearedevelopers.com/videos/100099-tour-de-force-open-source-llm-inference-optimization-from-simple-to-sophisticated) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Developer Experience, Platform Engineering and AI powered Apps](https://www.wearedevelopers.com/videos/990-developer-experience-platform-engineering-and-ai-powered-apps) - [Developing an AI.SDK](https://www.wearedevelopers.com/videos/198-developing-an-ai-sdk) - [Efficient deployment and inference of GPU-accelerated LLMs​](https://www.wearedevelopers.com/videos/929-efficient-deployment-and-inference-of-gpu-accelerated-llms) ## Related Articles - [MLOps – What’s the deal behind it?](https://www.wearedevelopers.com/magazine/125-mlops-what-s-the-deal-behind-it) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [MLops – Deploying, Maintaining And Evolving Machine Learning Models in Production](https://www.wearedevelopers.com/magazine/115-mlops-deploying-maintaining-and-evolving-machine-learning-models-in-production) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift)
